Abstract：The residual stress test of multi-manufacturer and multi-specification super13Cr tubing was carried out by using the commonly used blind hole method and ring cutting method，and 36 sets of residual stress test data were obtained. Based on the principle of statistics，the correlation analysis of residual stress obtained by the two methods was carried out.The results showed that there was a strong correl ation between the blind-hole technology and the ring method，and the result of the residual stress by blind-hole technology is about 20% different from the ring method.
